Any particular advantage to using json over xml with Flash
actionscript-3, comparison, flash, json, xml
Solution
JSON is typically a more efficient data encoding method than XML. This would matter if download time mattered to your application.
Another consideration is whether E4X query syntax has compelling advantages for your particular usage. It may be that you can do what you want by iterating over the results of a single query line, and the equivalent ActionScript code would be longer when interating over parsed JSON.
I would also consider whether this app has to interact with JavaScript code, such as because the Flash app lives in a browser and has to communicate with other things on the page. If so, I'd go with JSON, because dealing with XML in browser JS (as opposed to modern JS 1.8 with E4X) is much harder than dealing with JSON.
Problem
Well is there? From everything I've read, it seems like the answer is no,but was wondering if anybody has a differing opinion.
